dc.description.abstractThe study was undertaken to assess the quality status of drinking water in Tema municipal area. The concentrations of some selected toxic heavy metals (copper, zinc, nickel, cadmium, mercury, chromium, lead, iron, and manganese) were determined using Atomic Absorption Spectrophotometer. Among the nine selected heavy metals nickel and lead show higher concentration than the WHO recommended limits. This is an indication of pollution however their hazard quotients (HQ) of 0.04875 and 0.034938 is far less than 1. Besides, hazard index and incremental lifetime risk were calculated to be 0.0866 and 4.499 x 109 respectively. Since hazard quotient is far less than 1, and the risk value of 4.499 x 10-9 is also far less than 1 x 10-6 it implies no health risk is associated with the water and therefore their presence had no significant health effect on human life.en_US
